Obsessive-compulsive disorder (OCD) is a chronic, serious psychiatric disorder that affects 2%-3% of the population and is associated with high personal and societal costs. Genetic factors are estimated to explain roughly half the risk of developing OCD, and genomic studies are just beginning to identify common and rare genetic variants mediating this risk. A major goal of genomic studies is to yield insights into the etiology of OCD and identify molecular targets for the development of novel therapeutics. However, the overwhelming majority of subjects in existing genetic studies are of European ancestry, limiting the generalizability of these findings. To address …

ΔFOSB, an unusually stable member of the AP-1 family of transcription factors, mediates long-term maladaptations that play a key role in the pathogenesis of drug addiction, cognitive decline, dyskinesia, and several other chronic neurological and psychiatric conditions. We have recently identified that 2-phenoxybenzenesulfonic acid-containing compounds disrupt the binding of ΔFOSB to DNA in vitro in cell-based assays, and one such compound, JPC0661, disrupts ΔFOSB binding to genomic DNA in vivo in the mouse brain with partial efficiency. JPC0661 binds to a groove outside of the DNA-binding cleft of the ΔFOSB/JUND bZIP heterodimer in a cocrystal structure. Here, we generated a …

“You Can’T Post That!”: Constitutionality Of Non-Disparagement Orders Barring Divorced Parents’ Social Media Posts, Kaitlyn B. Hammond

Vanderbilt Law Review

When a marriage goes wrong, a court may use a non-disparagement order to prevent a party from speaking negatively about another in some way, either permanently or temporarily. Family courts often use non-disparagement orders to protect parties or their children from psychological harm during divorce or child-custody proceedings. In such cases, non-disparagement orders forbid parents from denigrating one another in front of their children and/or third parties. To protect the child, non-disparagement orders are often imposed upon both parents by the court. But courts do not always protect children and other parties from disparagement in this way. Although non-disparagement orders …

Verdict Format On Trial: Experimental Tests Of The Criminal Law’S Orthodoxy, Avani Mehta Sood

Vanderbilt Law Review

For centuries, American criminal courts have overwhelmingly favored “general” verdicts over “special” verdicts, without giving the latter a fair trial. A general verdict requires criminal jurors to deliver only an ultimate judgment of “guilty” or “not guilty” on a charged offense. In contrast, a special verdict would require jurors to answer a sequence of questions about whether each legal element of the charged offense has been proven beyond a reasonable doubt before they deliver a final judgment. The criminal law’s conventional wisdom holds that special verdicts will disadvantage defendants by constraining jurors’ latitude to temper or nullify the law, thereby …

Preempting Pre-Approval: Clarifying Preemption Doctrine For Product-Liability Suits Against Brand-Name Drug Manufacturers, Nicholas G. Wallenburg

Vanderbilt Law Review

One of the most important issues for product-liability lawsuits against drug manufacturers today is federal preemption. Plaintiffs injured by prescription drugs regularly turn to state tort law for a remedy. Defendants in these cases—often brand-name drug manufacturers—frequently invoke preemption doctrine to argue that the Food and Drug Administration’s (“FDA”) rigorous approval process for prescription drugs has displaced state causes of action. While the text of the Food, Drug, and Cosmetics Act does not clearly address this issue, the U.S. Supreme Court has relied on a so-called “impossibility” theory of preemption: When a drug manufacturer cannot comply with the duties imposed …

Tfeb Degradation Is Regulated By An Ikk/Β-Trcp2 Phosphorylation-Ubiquitination Cascade, Yan Xiong, Jaiprakash Sharma, Meggie N Young, Wen Xiong, Ali Jazayeri, Karl F Poncha, Ma Xenia G Ilagan, Qing Wang, Bei Gao, Hui Zheng, Nicolas L Young, Marco Sardiello

2020-Current year OA Pubs

Transcription factor EB (TFEB) is a master regulator of lysosomal biogenesis and cellular clearance pathways. TFEB activity is tightly controlled by multiple post-translational mechanisms, but the exact molecular mechanism controlling its stability has remained elusive. Here, we identify the IκB kinase (IKK) complex as a key regulator of TFEB protein stability through a phosphorylation-ubiquitination cascade. A high-content kinase inhibitor screen reveals that IKK inhibition increases TFEB protein levels, and genetic ablation of IKK components increases TFEB stability, upregulates lysosomal genes, and enhances lysosomal biogenesis and degradative capacity. Mechanistically, we show that IKK phosphorylates TFEB on a cluster of serine residues …

2020-Current year OA Pubs

INTRODUCTION: Recent advances in osteoimmunology have illuminated the significant role of neuroimmune interactions in bone and joint health. The neuroimmune system critically regulates bone cell function through a complex network of molecular mediators - including signals from the sympathetic and parasympathetic nervous systems, pro- and anti-inflammatory cytokines, cortisol and other hormones, and growth factors. These mediators interact within a nonlinear network where each component can influence others reciprocally, with the brain serving as a central coordinator.

AIM: Our goal in this narrative review is to: 1) Provide an overview of roles the neuroimmune system is involved in bone and joint …

Toward A Unified Framework For Open World Visual Learning, Yuansheng Zhu

Theses

Artificial intelligence systems have achieved remarkable performance across a wide range of visual tasks. However, most existing models operate under the unrealistic closed-world assumption, where training and test data are drawn from the same distribution. In real-world applications such as anomaly detection, autonomous driving, and medical diagnosis, learning systems frequently encounter novel or out-of-distribution scenarios. These settings require models that can recognize unknown inputs, adapt to new information over time, and maintain reliable performance under evolving conditions. This dissertation studies the problem of Open World Visual Learning, a paradigm that enables visual learning systems to operate robustly in dynamic and …
